Some twenty-five years before, in "With the Night Mail", Kipling had predicted that in a few years 'we shall hold the Sun level in his full stride.' But that was in gas-filled airships: the story refers dismissively to 'the years when men still flew tin kites over oil engines!'
This poem is dated 1929. This was a time when the science of aerodynamics and the technology of aircraft construction were advancing rapidly, enabling aeroplanes to fly at greater and greater speeds. But Kipling was still ahead of his time: on 12 September that year Augustus Orlebar raised the air speed record to 358 mph (575 km/h) in a Supermarine S.6 seaplane.
It was not until 10 March 1956 that the Fairey FD-2, flown by Peter Twiss, became the first aircraft to exceed 1,000 mph in level flight, at the same time raising the air speed record to 1,132 mph (1811 km/h). This was an astonishing increase of some 300 mph (480 km/h) over the record set the year before.

We can fly faster than gales and gulls. Only the Sun still goes round the world faster.
Light steals to uncurtain/ The dim-shaping skies Dawn is coming
We lift to the onset... Our plane takes off.
